Is it?

#1 When you do not have plans in outports...

#2 When long haul flights is not quite your cup of tea anymore...

#3 When you no longer crave for crew meals...

#4 When you prefer staying in Hong Kong to travelling elsewhere during consecutive days-off...

#5 When you fail to sleep during crew rest period...

#6 When there is no more anticipations...

Then maybe it is time to go...
